Have seen them fail. If infact it did break you probably have bent valves:frown: It is for sure an interference engine!

 

[jetmech]

No it didnt break, I wasnt sure if it was a chain or belt, Just thinking i should do it since it has 152000 miles on it. Ghall, thanks for the procedure, i take it i should be able to get any sprecial tools from autozone.

Don't bet on it.
Also, if it ain't broke, don't "fix" it.
